Progesterone supplementation after FET

Post by mcpb »

I am just curious if there is a definitive answer as to how long PIO injections are needed after a successful FET? There is so much variation out there from "it doesn't effect pregnancy outcomes at all" to continuing through the entire first trimester. Is there a standard number of weeks progesterone supplementation is needed specifically for a FET since no ovulation occurred and there is no corpus luteum to supply progesterone? Thanks in advance!

Unfortunately, there is no "standard" amount of time to continue progesterone support following a frozen embryo transfer cycle. In general, the placenta normally take over progesterone production around 7-9 weeks gestational age. Since there can be some variation in the timing of this, many centers continue progesterone support until 10-12 weeks gestational age. Other centers check your progesterone level throughout the early pregnancy to see if the medication can be tapered off earlier.
